Question

我正在尝试在Windows 7上的VMware Workstation上运行的CentOS 7.3系统集群上安装Kubernetes 1.9.0，遵循＆＃34; kubernetes-the-hard-way教程＆＃34;。当我进入教程中的验证阶段并尝试启动busybox部署（https://github.com/kelseyhightower/kubernetes-the-hard-way/blob/master/docs/12-dns-addon.md）时，pod状态仍然停留在＆＃34; ContainerCreating＆＃34;。

pod应该运行的节点的kubelet日志显示以下错误消息：

failed to get sandbox image \"gcr.io/google_containers/pause:3.0\":
failed to pull image \"gcr.io/google_containers/pause:3.0\":
failed to pull image \"gcr.io/google_containers/pause:3.0\":
httpReaderSeeker: failed open: failed to do request:

我将这两个域添加到/etc/docker/daemon.json中的不安全注册表列表中：

{
  "insecure-registries" : ["gcr.io"],
  "insecure-registries" : ["googleapis.com"]
}

Docker能够从命令行中提取图像：

docker pull gcr.io/google_containers/pause:3.0
Trying to pull repository gcr.io/google_containers/pause ...
3.0: Pulling from gcr.io/google_containers/pause

任何想法为什么kubelet无法拉动图像？

谢谢， TI

Answer 1

daemon.json中的语法是

"insecure-registries" : ["gcr.io" , "googleapis.com"]

“同样取决于您访问的注册管理机构，您可能需要按照here

的说明执行”kubectl create secret docker-registry ...“操作

最后，您可能必须通过在docker中创建一个包含证明here

的证书的新目录，将证书定义为/etc/docker/certs.d。

kubelet无法提取图像 - x509：由未知权限签署的证书
